βLord Marahal Dreirβ is a fabrication designed to hide the fact that one of the greatest Militarum officers of the modern age is actually a hyper-intelligent and patriotic Krieg Steed. What you see atop the steed (henceforth known as Steed Dreir) is actually one of many servitorised clones, stuffed into battledress and secured atop the real Lord Marshal. All of Dreirβs speeches are actually subvocalisations from Steed Dreir projected from a remote vox emitter within Dreirβs mask. The inherently muffled speech of Krieg soldiers helps to hide this fact. You notice how Dreirβs steed is always saved from grievous wounds and restored to health? Itβs framed as Dreir respecting and admiring his mount, but itβs actually because high-ranking members of the Militarum, Inquisition and Adeptus Terra find Steed Dreirβs battle expertise, strategic mind and ability to engage Kriegβs soldiery to be invaluable. It also helps to sell the so-called βimmortalityβ of the Lord Marshal, because if a Dreir clone is fatally wounded, they just make a new one for Steed Dreir to utilise. Theyβll even let Steed Dreir eat the old clones as a means of honouring them. Steed Dreir is, despite all of the tactical and social intelligence, still a Krieg steed, and clone meat is decently nutritious.
